AppCenter B15.0916.1 self-update InstUPD fails with .NET runtime error

[digitaltoast]

AppCenter wants to update itself, but the update always fails.

I have tried downloading a new version from the Gigabyte website, but the package is dated 2014, so that's no good.

Here are the errors in EventVWR:

Old thread, but to resolve, I would suggest uninstalling any app center components, then App Center itself, restart and attempt to install the latest version available for your board.  If this fails, you can troubleshoot why it won't install in your software environment.  Start with does the user account you are installing under have admin permissions.

Also helpful if you provide your hardware specs (board model at the very least) and the OS you are running.
